One of the great things about football is that sometimes numbers simply don't matter all that much.
While the scoreline is an obvious exception, other stats and figures can often prove meaningless on the pitch without an end product.
When it comes to World Cups, population size is one interesting number that often floats around in relation to teams, causing lots of comparisons.
Whether it's a side punching well above their weight or another unable to live up to crushing expectations, such figures can really put performances into perspective.

China did make it to the final round of AFC qualifying for the 2022 World Cup but only won one of their final 10 games to fall well short of making another appearance.
